      voxl-mavlink seems to support only MAVLink 2.
      https://gitlab.com/voxl-public/voxl-sdk/third-party/voxl-mavlink/-/tree/master/files

      The third-party application I use uses MAVLink1 in part, which results in an error (actually no response).
      Do you plan to support MAVLink v1.0 in the future?

        To reproduce:
        set MAV_PROTO_VER to 1 (always use version 1)
        VOXL cannot get any information from PX4.

          @JP-Drone Until now we didn't know that there was a use case for v1.0. What is the third party application?

            It's UgCS.
            The default is v1.0.
            It's possible to set v2 or auto.
            But if I set auto, it fails to connect.
            Because it tries to negotiate with v1 at first and VOXL doesn't handle it.

              @JP-Drone Does it work if you set it to v2?

                @Eric-Katzfey Yes, it works.
                I am not sure if changing the settings on the GCS side will affect the connection to other copter.
                But now it seems fine.
                Thanks.
